Make a clean copy of a source tree, like CVS export
hg clone source export rm -rf export/.hg
The same thing, but for a tagged release
hg clone --noupdate source export-tagged cd export-tagged hg update mytag rm -rf .hg
See diffs when editing commit message with VIM
Make a private copy of the 'hgeditor' script provided with mercurial and replace the call to the editor with following command:
vim "+e $HGTMP/diff" '+set buftype=help filetype=diff' "+vsplit $HGTMP/msg" || exit $?
This will start up VIM in vertical split mode with commit message in the left pane and diff in the right pane. The buftype=help setting for diff window tells vim to exit when all other windows are closed, so when you write and quit the log with :x (:wq - they are equivalent), vim exits. If you have syntax highlight set up, the diff will be properly highlighted.
This setting is suitable for wide terminals. If you have a narrow terminal, you may want to replace the +vsplit above with +split or add nowrap to the +set.
See diffstat of pulled changes
Place the following script (named "pull-diffstat" here) somewhere in your $PATH:
test -n "$NODE" || exit 0
PARENT=`hg parents $NODE | head -1 | awk -F':' '{print $3}'`
TIP=`hg tip | head -1 | awk -F':' '{print $3}'`
echo "diffstat for $PARENT to $TIP"
hg diff -r $PARENT -r tip | diffstatAdd a changegroup entry to the [hooks] section of hgrc:
[hooks] changegroup = pull-diffstat
Now you will see a diffstat of the new changes to your repo every time you do "hg pull".
One liner to remove unknown files with a pattern
To make these work, replace the ls -l with the command you wish to execute (ie. rm). You can also tweak the parameters passed to hg status to filter by something other than unknown files (see hg help status).
hg status -nu0 | grep -z pattern | xargs -0r ls -l
The above command requires a current version of GNU grep. If you don't have one, you can use the following:
hg status -nu | grep pattern | tr '\n' '\0' | xargs -0r ls -l
